Abstract

We employ a frequency comb to demonstrate a multiband wavelength-division-multiplexing (WDM)-based phase stabilization over a metropolitan-scale fiber link while maintaining a dark quantum channel. We achieve phase stability over 100 seconds, a four orders of magnitude improvement of the current state of the art.
